Are you owed money from your energy supplier? – Energy payment cycle explained

Millions of households pay their energy bills via a fixed monthly Direct Debit, which helps to smooth out costs over the year and is often the cheapest way to pay. However, what many people do not realise is that they could be owed money back from their energy supplier – and now could be the perfect time to claim what you are owed.

Fixed Direct Debit payments are set up based on your estimated annual usage, helping to spread out the payments evenly throughout the year. Given the significant energy price fluctuations and changes in how we use energy over the last few years, these estimates can often be wide of the mark. If your supplier has overestimated your usage, or if you've successfully cut down your consumption, you might have built up a significant credit balance without even realising it.

In this article, we explain why late spring/early summer is often the ideal time to check your energy balance. We also explain how the yearly cycle of energy use and billing works, the simple steps you need to take to get your money back and some important things you need to consider before you do. 

Why now is the perfect time to check your energy credit

Household energy consumption, especially gas for heating, peaks during the cold winter months and then drops significantly as the weather warms up in spring and summer. Data shows that the median daily gas usage can plummet from over 50 kWh per day in January to around 5 kWh per day in August. Electricity usage follows a similar, though less dramatic, pattern, falling from roughly 8 kWh per day in winter to 6 kWh per day in summer.

Those paying for their energy via a fixed Direct Debit tend to pay the same amount, month after month, aiming to average out the seasonal peaks and troughs. It means you'll typically pay less than you use in winter (drawing down credit or going into debt) and then pay more than you use in summer (building up credit).

By the time late spring arrives (around 1st May), the high-usage winter period is behind you. Your account should have stopped accumulating debt from heating costs, but you haven't yet built up the large credit buffer that accumulates over the summer months. This makes it the ideal time to assess your situation.

Excessive credit can build up for several reasons beyond the normal cycle: your supplier might have set your Direct Debit too high initially, your energy usage might have dropped (perhaps due to energy-saving efforts, a milder winter, or changes in your household), or previous billing errors might have been corrected, leaving a surplus.

If you have a significant credit balance at this point, then it could indicate that your Direct Debit is set too high, meaning past overpayments have created a surplus. Of course, this assessment hinges on having accurate, up-to-date meter readings and that your bills are being created and paid on time.

Understanding your energy bill

Understanding how your energy account balance naturally fluctuates throughout the year is key to knowing if your credit is excessive. Here's a breakdown of the typical cycle for someone paying by fixed monthly Direct Debit:

• Winter (approx. October - March) - This is peak usage time, mainly due to central heating. Your actual energy costs are likely higher than your fixed monthly payment. During this period, any credit built up over summer gets used, and your account balance will fall, potentially dipping into debt (a negative balance).
• Spring Transition (approx. April - May) - As the heating goes off, your energy usage drops sharply. Your fixed monthly payment now starts to exceed your actual energy costs. If you were in debt, it should stop increasing, or you might start building a small amount of credit. This period typically represents the lowest point, or 'trough', in your account balance across the year.
• Summer (approx. June - August) - Energy usage is at its lowest. Your fixed payment is significantly higher than your monthly energy cost, meaning you build up credit steadily each month.
• Autumn Transition (approx. September) - As temperatures cool, usage begins to creep up again. Your fixed payment might still cover the cost, but the rate at which you build credit slows down or stops. The credit accumulated over summer starts being used to offset the higher costs as winter approaches.

The energy supplier's goal when setting your Direct Debit is for your account balance to end up roughly at zero after 12 months, smoothing out those seasonal peaks and troughs. However, factors like changes to energy tariffs and prices, variations in weather and fluctuations in your own usage mean it rarely works out perfectly. Ofgem's rules require suppliers to set Direct Debits as accurately as possible, based on the best available information.

Are you owed money? How much credit is 'Too Much'?

The first thing to do is check your energy account balance. You can usually find this on your latest energy bill, by logging into your online account, or via your supplier's mobile app.

Crucially, this balance is only meaningful if it is based on actual meter readings, not estimates. Estimated bills can be inaccurate and lead to unexpected adjustments further down the line. If you don't have a smart meter, submit readings regularly (ideally monthly). If you do have a smart meter, it should send readings automatically, but it's worth checking your online account or bill to ensure readings are being received and applied correctly. 

In terms of working out whether you are holding too much credit in your account, a good rule of thumb is to check your account balance in late Spring (around 1st May). If you don't have a smart meter, then make sure you provide your latest accurate readings first. Then, if your account is in credit by more than the value of your fixed direct debit payment, then it may be worth speaking to your supplier and asking for some money back. 

How to claim money back from your energy supplier

The good news is that you have a right to get your money back if your account is in credit with your energy supplier. Energy regulator Ofgem's rules are clear: if your account is in credit, you can ask for a refund at any time. Your supplier must return the money promptly unless they have a 'fair and reasonable' justification for not doing so.

Steps to follow when claiming money back from your energy supplier

1. Check Balance & Submit Reading - Make sure your balance is accurate and based on a recent, actual meter reading.
2. Contact Your Supplier - Get in touch via phone, email, or check their website or app for an online refund request option. Some suppliers like British Gas, Octopus, and OVO offer easy online requests. Make sure you have your account number handy.
3. State Your Request Clearly - Tell them you've checked your balance based on an up-to-date reading and would like a refund of the credit. You can specify an amount if you don't want the full balance back. If you're unsure why the credit is so high, make sure you ask for an explanation.
4. Confirm Details - Ask how the refund will be paid (it is usually returned to the bank account that is used for the Direct Debit payments) and how long it will take.

How long will the refund take?

Suppliers are required to issue refunds 'promptly' for live customer accounts, although Ofgem doesn't set a strict deadline like they do for closed customer accounts. If your supplier refuses the refund, they must explain why, citing why they feel their decision is 'fair and reasonable'. Common reasons relate to needing the credit for upcoming winter bills.

It's worth noting that while rules exist, suppliers aren't always proactive in refunding credit on live customer accounts. Some may conduct annual reviews, but often the responsibility falls on the customer to check their energy account balance and actively request the money back.

If your supplier refuses unreasonably or doesn't respond, your first step is to make a formal complaint directly to them. If that doesn't resolve the issue, you can escalate your complaint for free to the energy ombudsman, which can conduct an independent investigation into the matter. 

Considerations before requesting a refund

Before you rush to reclaim your energy credit, consider whether it is the right move for your circumstances. While it is your money, claiming it back might cause further issues down the line.

Here are some key points to consider:

• Winter Bills Looming - This is the most common reason suppliers advise against taking full refunds, especially if you check later in summer or autumn. The credit built up over summer is specifically designed to cushion the blow of higher winter heating bills. Claiming a refund at the wrong time could lead to a sharp increase in your Direct Debit payments later, or leave you facing unaffordable bills or debt when winter arrives.
• Is Your Direct Debit Too Low? - If you find you're consistently in debt, even during late spring, your Direct Debit is likely set too low. Claiming back a small credit in this situation could mask the underlying problem and lead to bigger debt issues or problems switching supplier later. Focus on getting your payment amount corrected first.
• Estimated vs. Actual Readings - Never claim credit based on an estimated reading. Submit an actual reading first. The real balance could be much lower, or you might even owe money.
• Payment on Receipt of Bill / Quarterly Billing - If you pay for your exact usage when billed (e.g., quarterly), you shouldn't build up large credits like Direct Debit customers, unless you've overpaid or there's a billing error. The seasonal cycle applies to your usage, but not your payments in the same way. If credit exists due to an error, claim it back. Back-billing rules (no charges for usage over 12 months old if a supplier was at fault) still apply.
• Upcoming Price Changes - Direct Debits are usually based on current energy prices. If prices are predicted to fall significantly (like a future price cap drop), you might need less credit going forward. Conversely, if big price rises are expected, keeping a healthy credit balance might be prudent.
• Planning to Switch Supplier? - If you're switching soon, don't worry about claiming credit from your old supplier beforehand. They are legally required to refund it automatically within 10 working days of issuing your final bill. Focus on giving an accurate final meter reading.
• Cheap Fixed Deal Ending? - If you're coming off a low-cost fixed tariff onto a potentially much higher standard tariff or new fix, your monthly costs will jump. Keeping existing credit can help soften the impact of that first higher bill. In any case, you should consider shopping around to ensure you switch to the best available tariff when your deal ends.

Summary

Paying by fixed Direct Debit means your energy account balance will naturally fluctuate throughout the year, often building credit over summer. Late spring / early summer is typically the best time to check if this credit has become excessive and you have the right to reclaim money you're owed by your energy supplier, however, it pays to do your research.

Make sure that you fully understand the annual energy cycle and that your balance is based on actual readings. You need to consider the potential impact on your future bills – especially as you head into winter – before demanding the full amount back. If you run into problems getting a refund that you believe you're entitled to, or if your supplier isn't treating you fairly, don't hesitate to seek help from organisations like Citizens Advice or escalate your complaint to the energy ombudsman.
